Most likely the price for BTC this year will be lower than $ 20,000 and if you hold good coins, then do not sell these coins.
I also stick to the point that Bitcoin can unlikely reach $20,000 this year. It can reach $14,000 and in 2019 it can go higher than 2017 all-time high.
I do not even understand why you have such forecasts. Why all users predict a great future already in 2019, although today the crypto-currency market does not show any positive moments in stabilization and growth.
